[Lou] puts invisible fence inside and outside his home

Leave it to [Lou Wozniak] to go beyond ordinary when installing invisible fencing. Invisible fence is an electronic system that contains your dog by triggering a shock collar. The install requires a loop of wire to generate a field detected by the collar.

[Lou] starts off by buying a do it yourself kit. He has previous experience with this (check out his battery hack for the collars) and found that the cheap solid core wire didn’t hold up to animals and shovel accidents. He headed down to the hardware store and came back with a spool of stranded wire with extra thick insulation which should hold up much better.

The image above shows the model he built to plan for the installation. He’s not just making a single area in the yard. Look closely and you’ll see he’s going to use it to keep the dogs out of the dining room as well. This loop will be installed just below the floor from the basement.

With planning behind him he doesn’t fail to innovate with the installation technique. He recommends an angle grinder with a diamond blade to cut the slot for the wire in your yard. The one caveat being that you need to wait until the yard is super dry or it will muck up the blade. Dry dirt creates a lot of dust, but he uses a leaf blower or floor fan to blow it away from him as it works. To help minimize the amount of shocks the dogs receive while learning their new area he placed some white rope above the wire run as a visual cue.

Genezap improves your video game skills using corporal punishment

As if getting your ass handed to you while playing video games wasn’t annoying enough, [furrtek] decided that the best way to help improve his skills was by inflicting physical pain each time his on-screen character died.

While perusing the Internet looking for something to break through the doldrums of the day, he came upon a video in which someone decided to try on a dog shock collar just for kicks. This sparked [furrtek’s] imagination, and he started to think that it would be pretty cool to use the same sort of device to make dying in a video game that much more unpleasant.

After ordering a set of collars online, he tore them apart to see how they functioned, and to measure just how big of a jolt they were able to deliver. [furrtek] then modified two Genesis controllers with a pair of ATtiny 25s, which let him send the fire signal to the collars. Unfortunately, stock Genesis games don’t allow you to send signals to the controllers, so [furrtek] had to spend some time hacking ROM images to trigger events when players are injured or lose a life.

We think the project is pretty slick, and if you don’t mind fiddling with your old controllers, you too can have a merciless trainer strapped around your neck. For those slightly more averse to pain, you can watch [furrtek] and his friend [Dyak] suffer the consequences of poor gameplay for your amusement.
